Cell Signaling Pathways activated by Hydrogen Peroxide


1. Mode of action of Pathway
The process of cell signaling through hydrogen peroxide is a very sensitive approach that initiates itself with determined pathways. This is a mode noted through redox signaling, where there are many receptors acting by the means of NADPH oxidase (NOX) in order to create reactive oxygen species, like those of superoxide radical (O2−•) added by hydrogen peroxide (H2O2). This activity is subject to regulate determined action of signaling proteins like those of tyrosine phosphatases, led by transcription modes and ion channels. It is the O2 −• participation in nitrosylation reaction that leads to determined Pathway 7.
